I had a couple of Nexus 7 tablets lying around, so I built a simple single page app for controlling my Home Assistant with those: https://github.com/elysion/homeassistant-daydream.
You can select the sensors, scenes, switches and lights to be shown in the UI in a per device (/browser) basis. I have one tablet in my living room and the other in my office sitting on a dock and configured to use the Website Daydream to display the webpage. As I have the screens on all the time, I tried to keep the UI quite minimal in order for it to not be distracting. Here’s how the UI looks:
In order to get the app to work, you need to have a node setup for building the project and a web server for hosting the built files. There are instructions for this in the Github repository.
Anyway, thought this might be useful also for others and wanted to share it. Hope you like it
